  • Table of Contents

In recent years, the demand for anode material has been rapidly increasing as the battery capacity required for smartphone applications has exceeded 3,000 mAh, and tablets and Ultra PCs adopt a high-capacity lithium polymer battery of 4,000 mAh or higher. Moreover, increasing demand for mid- and large-sized battery for electric vehicles (xEVs) and ESS applications is shifting the focus of anode materials from carbon- and graphite-based to silicone -based material (metal complex). In this regard, new entrants to develop and mass-production Si-anode materials continue to appear.

Si-based high-capacity materials are currently being developed only by a few companies. However, in order to overcome the driving range issue of electric vehicles, it is essential to develop high-capacity batteries. Hence, identification of the current development status and limitations in advance will ensure competitiveness in the field. Si-anode materials are expected to grow at an annual average of 55% by 2030. The proportion of Si-anode materials in the overall anode market is expected to increase from 1% in 2019 to 7% in 2030.

The most representative high-capacity anode materials for lithium secondary batteries are Si-C composite, Si-alloy, and SiOx. Among them, SiOx and Si-alloy technologies are most matured for commercialization and applied for the development of high-capacity batteries by a few battery makers. However, there are still issues to be resolved, including short lifetime, and swelling. The number of new technologies reported in industry and academia and focused research of anode material makers could be promising indicators for successful commercialization of the technology in the near future.

This report describes technology development trends and performance improvement of Si anode for xEV, ESS, and IT applications. Particularly, the most recent development status of Si-based high-capacity anode materials [Si-alloy, SiOx, Si-C composite] is surveyed. In addition, the ongoing efforts to apply the new anode materials to batteries, relevant technical issues, and possible solutions are elaborated to facility the development of high-capacity batteries.

The strong points of this report include,

  • 1. Overall technology development status of anode material for lithium secondary battery
  • 2. Core technology elements and current issues of high-capacity Si-based anode materials
  • 3. Recent technology development trend for Si-based anode materials
  • 4. Prospect for potential applications and commercialization of Si-based anode materials
